How many grams of CaF2 are present in 1.25 L of a 0.15 M solution of CaF2? How do I find the grams I am confused on that part?

Mass = 14.64 g

Explanation:

Given dа ta:

Volume of solution = 1.25 L

Molarity of Solution = 0.15 M

Mass of CaF₂ = ?

Solution:

Molarity is used to describe the concentration of solution. It tells how many moles are dissolve in per litter of solution.

Formula:

Molarity = number of moles of solute / L of solution

We will calculate the number of moles of CaF₂ and then determine the mass by using number of moles.

0.15 M = number of moles of solute / 1.25 L

number of moles of solute = 0.15 M * 1.25 L

number of moles of solute = 0.1875 mol/L * L

number of moles of solute = 0.1875 mol

Mass in gram:

Mass = number of moles * molar mass

Mass = 0.1875 mol * 78.07 g/mol

Mass = 14.64 g
